Lette/rs Patent No. 92,800, dated July 20, 1869.

IMPROVEMENT IN CURRENT-WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame:

,fcathering arrangement of the buckets, calculated to adapt the wheelfor application to the current, either transversely or longitudinally;also for spreading the buckets to be acted on by the water, or foradjusting them, so as not to be acted on, as hereinafter more fullydescribed.

Figure l represents a plan view of my improved wheel when adjusted foraction transversely of the current.

Figure 2 represents a perspective View when adjusted for applicationlongitudinally.

Figure 3 represents a side elevation with the buckets adjusted so as notto have motion from the water Similar letters of reference indicatecorrespomlini.; parts.

A represents the shaft, which I support on any suitable raft or iioat B,with one end overhanging the said iioat, and supporting the buckets orvanos C, upon the radiating arms D, firmly fixed in a hub, E. The. saidvanes are connected to the arms by bands or loops F, looping around thearms in a manner to permit the vanes to oscillate freely for featheringor adjusting the sides ofthe vanes, either parallel witlrthe shaft orobliquely thereto.

I connect each vane, near the hub of the wheel, by

links or rods G, to thc rim of a sliding-collar, H, which rotates withthe shaft.

To this collar I connect a shifting-lever, I, by a rod, K, so arrangedthat I may slide the collar for adjusting the vanos while in motion, andin this way I may ,open oradj ustthe bucket-sto receive the force of thewater, or adjust them edgewise thereto, s0 as not to be exposed to it.
